After the switch in is closed on point a, there is current i through resistance r. gives the current for four sets of values of r and capacitance c

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
